If you order a product in amazon of which the seller is Cloudtail seller - Hyderabad, then they might ship your product through India Post courier.
At such cases,generally your product will be first shipped through amazon upto the nearest India Post center located near your delivery address.

So, until the parcel reach the nearest India post destination, the status cannot be tracked accurately through India-post website.

Rather, you can directly track the status of your amazon ordered product through Amazon website or Amazon app in My Orders section.

But once the delivery is under the control of India post , then you can get the detailed tracking status from India Post website by providing the AWB or consignment number.

If the product is shipped as gift from other person, then you should know the AWB number to track the delivery status of the product. In such case, you dont need to log in to the amazon account to track the status.
